(Medical Xpress)—Membrane fusion is a highly regulated event, both inside cells, and between them. From the moment a sperm first fuses with an egg, subsequent developmental events depend upon its proper control. Inside ...
(Medical Xpress)—Human bone breaks down and regenerates naturally all the time, in a perfectly balanced dance that maintains skeletal integrity.

Bone health requires a balanced activity of various bone cell types including bone-forming osteoblasts and bone-resorbing osteoclasts. Osteoporosis occurs when osteoclasts dominate without adequate bone formation to compensate. ...

Most existing treatments for pathological bone loss inhibit osteoclasts (bone-destroying cells) to limit bone degradation. However, by doing this, they also prevent bone formation since it is stimulated by the presence of ...

Bone integrity requires skeletal remodeling, which involves both bone formation and resorption. It has been previously shown that the formation of new bone is triggered by degradation of older bone. However, it is unknown ...
